Competition For Resources

The interest in the border of viability originated from various sources, including legal requirements, the rejection of technical life support, competition for resources, concerns about handicaps, and proximity to the fetus with its limited rights. Gestational age was determined from menstrual history by Hippocratic writers, who established the tenacious idea that 7-, but not 8-month-old infants could survive. Naegele’s rule, already published by Boerhaave in 1744, was correct when applied to the last day of menstruation. Birthweight and length were not measured until the end of the 18th century. This remarkable disinterest resulted from superstition, grossly inaccurate measurements by the authorities Mauriceau and Smellie, and the conversion chaos of the pre-metric era. A table is provided with historic mass and length units to allow determination of birthweight and body length in the older literature. The idea of viability is a remnant of vitalism, a medical doctrine popularized in 1780 by Brown. Many short-lived statements defined its border, but until now what was meant by viability remained nebulous.

Objectives: to compare the accuracy of equations F.P. Hadlock and computer programs by V.N. Demidov in determining gestational age and fetal weight in the third trimester of gestation. Materials: 328 patients in terms 36–42 weeks of gestation are examined. Ultrasonography was performed in 0–5 days prior to childbirth. Results: it is established that the average mistake in determination of term of pregnancy when using the equation of F.P. Hadlock made 12,5 days, the computer program of V.N. Demidov – 4,4 days (distinction 2,8 times). The mistake within 4 days, when using the equation of F.P. Hadlock has met on average in 23,1 % of observations, the computer program of V.N. Demidov — 65,9 % (difference in 2,9 times). The mistake more than 10 days, took place respectively in 51,7 and 8,2 % (distinction by 6,3 times). At a comparative assessment of size of a mistake in determination of fetal mass it is established that when using the equation of F.P. Hadlock it has averaged 281,0 g, at application of the computer program of V.N. Demidov — 182,5 g (distinction of 54 %). The small mistake in the mass of a fetus which isn't exceeding 200 g at application of the equation of F.P. Hadlock has met in 48,1 % of cases and the computer program of V.N. Demidov — 64,0 % (distinction of 33,1 %). The mistake exceeding 500 g has been stated in 18 % (F.P. Hadlock) and 4,3 % (V.N. Demidov) respectively (distinction 4,2 times). Conclusions: the computer program of V.N. Demidov has high precision in determination of term of a gestation and mass of a fetus in the III pregnancy.

The objective of this study was to predict bodyweight and estimate body measurements of Limousin cattle using digital image analysis (DIA). Body measurements including body length, wither height, chest depth, and hip height of cattle were determined both manually (by measurements stick) and by using DIA. Body area was determined by using DIA. The images of Limousin cattle were taken while cattle were standing in a squeeze chute by a digital camera and analysed by image analysis software to obtain body measurements of each animal. While comparing the actual and predicted body measurements, the accuracy was determined as 98% for wither height, 97% for hip height, 94% for chest depth and 90.6% for body length. Regression analysis between body area and bodyweight yielded an equation with R2 of 61.5%. The regression equation, which included all body traits, resulted in an R2 value of 88.7%. The results indicated that DIA can be used for accurate prediction of body measurements and bodyweight of Limousin cattle.

The α-fetoprotein (AFP) concentration in serum is an indicator of gestational age in preterm infants.1 IgM and IgA concentrations are helpful in the diagnosis of perinatal infections.2,3 Determination of all three protein levels can conveniently be made from one single microhematocrit capillary tube. The small blood volumes involved and the simplicity of the procedure make it a tool for routine use in newborn nurseries. The technique described can also be used for the determination of many other compounds. MATERIALS Heparinized microhematocrit capillary tubes (Propper Manufacturing Co., Inc., Long Island, N. Y.) are 75 mm long and have an internal diameter of 1.1 to 1.2 mm.

Female Ambition

Este trabalho tem por objetivo apresentar um estudo sobre a questão da liberdade das mulheres e as limitações que sofriam e sofrem por diversas questões relacionadas à determinação de papéis sociais para os gêneros. Nossa fundamentação teórica principal é a obra de Elisabeth Badinter, especialmente Emilie, Emilie:a ambição feminina no século XVIII(2003). Badinter pesquisou e reflete sobre as restrições sociais que as mulheres sofriam no século XVIII. A consequência deste processo é que a iniciativa de se tornarem cientistas, escritoras, diplomatas, magistradas e outras funções similares, eram consideradas ruins para a sociedade, uma vez que a ambição feminina, causaria desordem na sociedade, por não condizer com a natureza das mulheres. Além disso, este trabalho analisa também artigos sobre a participação das mulheres nos programas de pós-graduação em Filosofia no Brasil que apresentam a redução da proporção de mulheres na medida em que se aumenta o grau de especialidade das pesquisas. Palavras-Chave: Filósofas. Mulheres. Filosofia. Feminina. Pós-Graduação. Abstract This paper aims to present a study on the issue of women's freedom and the limitations they have suffered and suffer for various issues related to the determination of social roles for genders. Our main theoretical foundation is the work of Elisabeth Badinter, especially Emilie, Emilie: the female ambition in the 18th century (2003). Badinter researched and reflected on the social restrictions that women suffered in the 18th century. The consequence of this process is that the initiative to become scientists, writers, diplomats, magistrates and other similar functions was considered bad for society, since the female ambition, it would cause disorder in society, for not matching the nature of women. In addition, this work also studies articles on the participation of women in postgraduate programs in Philosophy in Brazil which show a reduction in the proportion of women as the degree of research expertise increases. Key words: Philosophers. Women. Philosophy. Feminine. Postgraduate.

Accurate gestational age determination is very important for management of continuation and termination planning of the pregnancy. rd To establish placental thickness as a parameter for determination of gestational age and fetal growth pattern at 3 trimester. 100 primigravida women who are fullling the inclusion criteria and attend gynae &obs OPD or admitted in their third trimester at IPGME&R from January 2017 to june 2018. Placental thickness at 3rd trimester USG scan is moderately correlated with gestational age, if placental thickness expressed in millimeter then it correlated with gestational age at weeks. rd st Placental thickness with >3.2 cm (32 mm) at 3 trimester almost associated with good fetal outcome, with APGAR score >8 at 1 min and birth weight >2500 gm.
